The unique attributes of fiberglass also make it naturally resistant to corrosion and staining. That’s why fiberglass windows and doors are popular choices for coastal climates where saltwater breezes abound and industrial applications can emit particulates that can reduce the lifespan of some finishes on building exteriors.

Fiberglass substrates are electrically non-conductive and therefore eliminate galvanic corrosion, including concerns connected with coastal environments. In fact, fiberglass is often used in underground mines for everything from bolts to doors.
